WINDOW FRAME AND SASH.

SPECIFICATION forming part of Letters Patent No. 482,989, dated September 20, 1892.

Application filed April 1, 1892. Serial No. 427,398. (No model.)

To all whom it may concern:

Be it known that I, J AMES WILSON, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Window Frames and Sashes; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of window-frames in which the sash-confining parts of the casing or frame are so constructed that they can be moved out of the way to permit the removal of the sashes.

My invention consists of the constructions and combinations of parts hereinafter fully described and claimed.

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a horizontal cross-section of onecorner of frame and sash. Fig. 2 is an elevation of the inner side of the frame, the sashes being removed. I

A is the frame or pulley stile.

B is the lower sash.

O is the upper sash.

D is the inside stop.

E is the parting-strip, and F is the outside stop.

The stile A is offset at its outer side, as shown at a, in order to allow the parting-strip E to turn inwardly against its face and to be out of the way of the upper sash in removing it.

The parting-strip E either throughout its whole length or only the lower section thereof, which is severed from the upper portion at about the middle, is hinged to the stile A at c, as shown. When in place, the parting-strip extends outwardly along the offset of stile A and projects far enough beyond it to serve its purpose between the two sashes, and when turned inwardly it lies along the face of stile A and is out of the way of the upper sash,

wherebysaid sash can be removed inwardly. It will thus be seen that the pulley-stile A must be made with the offset a to properly locate and hinge the partingstrip, and to accommodate the sashes to this construction of stile the upper sash is made narrower than the lower sash, as shown. This is done simply by a difference in the width of the sash-stiles.

The inside stop D or a lower severed section thereof is hinged to the pulley-stile atcl, as shown, and said stile where the stop hes against it is inclined or beveled, as shown at a, in order to allow the stop when thrown back to be out of the line of movement of the sash in removing it. This bevel also serves to prevent the inner edge of the stop from binding or cramping on the sash in moving to or from it about its hinge.

The hinged parting-strip is latched when in place by means of apivoted catch G, seated in the pulley-stile and projecting from the face of its offset Ct. This catch is controlled by a spring 9, and it is adapted to engage a latch -plate 6', seated in a recess c made through the parting-strip. The catch is accessible from the outer side of the recess, and by inserting the finger it can be lifted and the parting-strip released.

The operation is as follows: To remove the lower sash, the inside stops D or their lower sections are thrown back, whereupon the sash is free and can be easily taken from the frame. To remove the upper sash, it is drawn down to the lower half of the frame. The recesses e in the lower sections of the parting-strips being exposed by the removal of the lower sash, the finger can be inserted to lift the catches G. The parting-strips being now free can be swung inwardly and the upper sash can then be removed.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a window frame and sash, and in combination with pulley or frame stiles and sashes fitted thereto, parting-strips hinged to said stiles and adapted to be turned out of the way to permit the removal of the upper sash from the frame and spring actuated catches for engaging and securing said strips, substantially as herein described.

2. In a window frame and sash, and in combination with pulley or frame stiles and sashes fitted thereto, the parting-strips and the inside stops, each hinged to the stiles, whereby they may be turned out of the way to permit the removal of the sashes from the frame, said inside stops having an inclined or beveled face engaging a like face on the frame, and springactuated catches for engaging the parting strips, substantially as herein destiles and adapted to be turned to or from scribed. the ofisets, the catches seated in said ofisets, 3. In a window frame and sash, and in comand the latch-plates seated in open recesses bination with the pulley or frame stiles havin the parting-strips, substantially as herein :5 5 ing beveled or inclinedinner faces, the inside described.
